Rails 6神社image_tag已损坏，但在新标签中打开不是

Question

使用 Shrine 启动了一个全新的 Rails 6 应用程序，一切都是全新的，跟随入门指南。成功上传文件，但在显示页面上，img 标签只是一个损坏的图像图标，但如果我在新选项卡中打开它，它会显示。控制台中没有显示错误。

/config/initializers/shrine.rb

require "shrine"
require "shrine/storage/file_system"

Shrine.storages = {
    cache: Shrine::Storage::FileSystem.new("public", prefix: "uploads/cache"), # temporary
    store: Shrine::Storage::FileSystem.new("public", prefix: "uploads")      # permanent
}

Shrine.plugin :activerecord           # loads Active Record integration
Shrine.plugin :cached_attachment_data # enables retaining cached file across form redisplays
Shrine.plugin :restore_cached_data    # extracts metadata for assigned cached files

app/uploaders/image_uploader.rb

class ImageUploader < Shrine
  # plugins and uploading logic
end

app/models/content.rb

class Content < ApplicationRecord
  include ImageUploader::Attachment(:image) # adds an `image` virtual attribute
end

views/contents/show.html.erb

<p>
  <strong>Image:</strong>
  <%= image_tag @content.image_url %>
</p>

想通了。我从 Imgur 中提取了我正在测试的“gif”，它实际上是一个 mp4，因此不会显示在“image_tag”中。将其更改为“video_tag”并且它正在工作。
